bee.nvidia.mode=gsp-off loads the driver with NVreg_EnableGpuFirmware=0 and
skips nvidia-uvm/nvidia-modeset, so CUDA (nvbandwidth/dcgm/nccl) can't run —
and on Hopper H200 GSP is effectively mandatory anyway, so the mode is dead
weight in this test image. Remove it from every boot entry. fail-safe is now
bee.nvidia.mode=normal pci=realloc iommu=pt, so the GPUs come up with uvm and
the GPU test actually runs under iommu=pt (the point of the entry). All four
sources (grub.cfg + live.cfg.in templates, build.sh write_canonical_*) match.
The internal GSP auto-fallback in bee-nvidia-load (normal mode, GSP init
hangs >90s → retry with EnableGpuFirmware=0, then still load uvm) is left
intact — it serves converted SXM->PCIe cards on other test targets and keeps
CUDA working, unlike the removed explicit menu mode.
